CONFIG: improvements to mpirunDebug

- the '-no-core' to limit coredumps to zero size
- the '-quick' option, which changes valgrind --leak-check from "full"
  to "summary", and implies -no-core as well.
- enforce tcp libfabrics provider under valgrind since valgrind
  does not otherwie work nicely with RMA
